PPR PipesApplication
- Comprehensive, ecological all-plastic system for indoor hot and cold water installations.
- Corrosion resistant pressure pipe.
- Metric series sizes 20mm to 200mm suitable to use at temperatures up to and including 95oC.
- Pressure rating PN-10 to PN-20.
- Generally resistant to most acids, bases, salts, aliphatic solutions, oxidants, and halogens.
- Typical applications includes: chemical processing, potable water systems, food processing, water and waste water treatment, conveyance of air and other industrial applications involving corrosive fluid transfer.
Scope
Outlined specification DIN 8077 / 78. This pipe is intended for use in applications where the fluid conveyed does not exceed 95°C.
PP-r Materials
The material used in the manufacture of the pipe shall be domestically produced Polypropylene co-polymer compound with other additives.
PP-R grade AER003N of Reliance Industries Ltd.
Dimensions
PP-R Pipes shall be manufactured in strict accordance to the requirements of DIN:8077/78 for physical dimensions and tolerances. Each production run of pipe manufactured in compliance to this standard, shall also meet or exceed the test requirements for materials, workmanship, creep strength, impact strength, heat reversion, density, melt flow index etc..

Polyfusion welding:
Step 1: Cut the pipe upright to the axis of the pipe.
Step 2: Clean the die surface properly and ensure machine temperature has reached to 260°C.
Step 3: Insert pipe and fitting into respective die and allow to heat as per table given above.
Step 4: Remove the pipe and fittings from the dies and immediately push the pipe into the socket and allow it to cool as per table given above.
